Restore Full Functionality to Your GM Truck or SUV
Are you battling bizarre electrical issues in your vehicle? Flickering lights, malfunctioning power windows and locks, a security system that acts up, or warning lights that won’t turn off are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating problems. This replacement BCM is the definitive solution to get your truck or SUV operating correctly again.
Is Your BCM Failing? Common Symptoms:
- ✔ Erratic or non-working power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ The security or anti-theft light flashing, preventing the vehicle from starting.
- ✔ Inconsistent or non-functional dashboard gauges.
- ✔ Radio or climate control systems working intermittently.
- ✔ False warnings on the driver information center.

Important Installation Notes:
While this BCM is programmed for your vehicle, certain integrated safety systems may require a ‘relearn’ or synchronization procedure after installation. This is a standard part of the repair process for many modern vehicles.
- Airbag System (SRS): If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake System: A Brake Pedal Position sensor relearn might be necessary on some models to ensure correct brake light and traction control operation.
There is no core charge for this part. You can keep your old module without needing to send it back.
Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s VIN during or after checkout, and the module will arrive ready for installation.
What does the BCM actually control?
The Body Control Module manages a wide array of non-engine related functions, including power windows, locks, interior and exterior lighting, the security system, wipers, and often communicates with the radio and climate controls.
What if the airbag light comes on after I install it?
This is a normal possibility. The new BCM needs to be electronically introduced to the airbag system. A technician with a capable diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Is this a difficult part to replace?
The physical replacement is typically straightforward, as the BCM is usually located under the steering column or in the center dash. However, due to the potential need for post-installation electronic relearn procedures, we recommend professional installation or for the work to be done by an experienced DIYer with access to a high-level scan tool.
How do I find my original part number?
Your original part number is printed on a sticker on the BCM itself. However, as long as your vehicle is listed in our fitment chart, this module will work, as we program it based on your VIN, not the old part number.
